Three-dimensional CT angiography of the splenic-portal venous system by using multiple threshold display.
We assessed the three-dimensional (3D) CT angiographic reconstruction of the splenic-portal venous system obtained by using multiple threshold display (MTD) in 40 patients with liver disease. In each patient, both shaded surface display(SSD) and MTD images were generated by using an Xtension with a Sun SPARCstation 20, and they were compared by two radiologists. MTD image quality was superior to that of SSD images, because MTD diminished longitudinal direction artifacts and the image depicted the small vessels clearly. Based on the above results, we consider MTD to be a useful method for 3D-CT angiography of the splenic-portal venous system.
